Execpt you want the 5 HP engine to put away at about
1500 RPM with a nice quite muffler, and run about a
three to one belt/gear drive to get the alternator up to
the 3K to 4K rpm range. In that configuration your 5 HP
engine is more like a 2 HP engine, and it will run for
a very long time and very efficiently.

A standard 60 amp alternator will deliver 750 watts,
and you could always get an old cop alternator that
does twice that. Diesel cars also have beefed up
electrical systems. I had a diesel Rabbit years ago
that had an 80 amp alternator.

In any case, with plenty of battery storage, you would
just size things for your average anticipated load.
